I recently read this book which was published in the 70s. I found it very helpful on this much neglected ministry of deliverance. I was for years very critical of the belief that believers in Jesus can be indwelt by demon spirits, but this brief Q&A booklet brought to light what the scriptures teach. He illustrates his teaching with real life accounts of exorcisms and how people were set free from spirit entities that tormented them. He acknowleges that demons are not a trustworthy source of info and that they are not to be dialogued with as is done in many instances.
It is not exactly a manual i.e. a how-to-book but it answers many questions about demons and deliverance. The answers to the questions about Christians and demons and what, if any, influence demons may have on born again Christians is done quite well. As one who has been in the deliverance ministry for many years I really like these answers especially for those who criticize the ministry of deliverance. Also, the answers give much insight into the reasoning for the deliverances. firstname.lastname@example.org
